Dinos graze in a jungle sprouting atop an old Charleston building. Down on the street, cars idle, ready to vroom up the walls and into the trees. In a child’s world, anything can happen. The same can be said for a container garden designed to encourage play—and nurture little growers’ knowledge about the natural world.

To make a kid-friendly planter of your own, think up a theme that will appeal to your child. Creating three site lines—say, a street level, a rooftop, and a tree canopy—will offer them more options to explore and relate.

Then select a container (with drainage holes) large enough to accommodate both plants and toys. We turned ours into a building by snapping a photo of windows at The Citadel that we printed on water slide decal paper. After applying the decals to the pot, we sealed them with acrylic spray.

Now, pick your plants. Look for varieties that enhance the container’s theme, and be sure to include a few with intriguing textures and scents (but teach children not to taste them!). In the rooftop dino oasis:

Ask an Expert: When it comes to fertilizing, what are the bare-minimum musts?

“It’s helpful to start with a soil test, which will identify any nutrient deficiencies and help you target correct applications.

Organics such as compost and mulch will break down over time and build soil structure, ultimately creating humus that is ideal for successful gardening. Knowing your specific plants’ needs is key as well. For fruiting trees, look for fertilizer spikes formulated for specific varieties’ nutritional requirements. To boost showy annuals’ blooms, use Miracle-grow Liquidfeed, which attaches right to your hose. For everything else, look to organic fertilizers such as Espoma Tones.”
